Plea of the Birds

This episode becomes available after earning 38 stickers. Accept the quest from the sign to speak to Cinderella. She will ask you to help the birds of the forest.

All you have to do is go through the forest and defeat 50 ghosts. You've fought these types of ghosts in past episodes, so it's nothing new. It doesn't matter which path you take first. All three paths lead to a dead end with a boss ghost - three boss ghosts in total.

Defeat all 50 ghosts to end the quest. If you're short, you probably missed the ladder leading downward at the southeast part of the forest. Remember to investigate all sparkling objects.
